FMLA retaliation

They can. Intermittent FMLA actually encourages you to work with your employer to make it the least disruptive for them(not the exact wording by any means, but my interpretation.) Its very understandable that it would be difficult to have you miss every Sunday. Your daycare issues are your issues, not your employers.
You can easily google intermittent FMLA to read their exact wording.

 

The dirty little secret is that the government (like most entities) focuses more on the needs of its biggest funding sources.
That's why corporations pay a tax rate significantly below the average working stiff.
Plus, FMLA is meant to be an opium to appease the masses, just as those EEOC laws.
The government is not your friend, its your master.

 

It is not unreasonable to adjust them granting you an accommodation in a manner that will disrupt operations in the least significant manner.

 

In designing an intermittent leave schedule, the employee must try to accommodate the employer's schedule & needs. The employer may even temporarily assign the employee to a different position with equal pay & benefits to accommodate the intermittent schedule.

It is up to you to accommodate the employer's needs. Day care issues is not your employer's concern - sorry.

 

"Employees needing intermittent/reduced schedule leave for foreseeable medical treatment must work with their employers to schedule the leave so as not to unduly disrupt the employer's operations, subject to the approval of the employee's health care provider. In such cases, the employer may transfer the employee temporarily to an alternative job with equivalent pay and benefits that accommodates recurring periods of leave better than the employee's regular job."

This is from the DOL site.

 

This is totally legal. If you are missing one shift a week, that is not reasonable. If your employer knows you can't work that day, then it only makes sense to change your schedule so you are working when you are able to work. Every parent has to figure out day care so that is hardly unique to you nor the kind of deterrent that the law prohibits.
