Income Taxes	6 Months Ended
Jul. 01, 2017
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We recorded income tax (benefit) expense of $(1.1) million and $0.6 million for the three months ended July 1, 2017 and June 25, 2016, respectively, and $(0.9) million and $0.6 million for the six months ended July 1, 2017 and June 25, 2016. The tax benefit recorded for the three and six months ended July 1, 2017 primarily related to the excess tax benefits from the taxable compensation on share-based awards, partially offset by tax expense pertaining to amortization of goodwill associated with the acquisition of Care.com HomePay for tax purposes, for which there is no corresponding book deduction, and certain state taxes based on operating income that are payable without regard to tax loss carryforwards. Prior to January 1, 2017, we recognized the excess tax benefits of stock-based compensation expense as additional paid-in capital (“APIC”), and tax deficiencies of stock-based compensation expense in the income tax provision or as APIC to the extent that there were sufficient recognized excess tax benefits previously recognized. As a result of the prior guidance that excess tax benefits reduce taxes payable prior to being recognized as an increase in paid in capital, we had not recognized certain deferred tax assets (all tax attributes such as loss or credit carryforwards) that could be attributed to tax deductions related to equity compensation in excess of compensation recognized for financial reporting. As of January 1, 2017, we had generated federal and state net operating loss carryforwards due to excess tax benefits of $2.2 million and $1.9 million, respectively. Effective as of January 1, 2017, we adopted a change in accounting policy in accordance with ASU 2016-09 to account for excess tax benefits and tax deficiencies as income tax expense or benefit, treated as discrete items in the reporting period in which they occur, and to recognize previously unrecognized deferred tax assets that arose directly from (or the use of which was postponed by) tax deductions related to equity compensation in excess of compensation recognized for financial reporting. No cumulative transition adjustments were recorded to accumulated deficit as a result of this change in the accounting policy, as we had previously maintained a valuation allowance against our deferred tax assets that could be attributed to equity compensation in excess of compensation recognized for financial reporting.
