Are 'day off'' and 'take it easier' correct?

[Tan Elaine]

The following is from a local newspaper.

There has been some feedback from bus drivers that they are clocking more overtime on their day offs. Some drivers, especially the younger ones, prefer more work, others prefer to take it easier.

Are 'day offs' and 'take it easier' correct? I have heard of 'take it easy' and 'day off''.

Thanks.

I'd say 'days off'. I'd probably also just say 'take it easy', but I think 'easier' is acceptable.
