@Cerberus if for minor language you mean the 17th most spoken language in Europe, with 10 million native speakers... Then I guess yes, it's a minor language.

@O.R.Mapper But the OP says "Since I am losing around 8-10 hours a week going to and from the office [...] I am likely to get less work done, not more" which kind of implies that commuting will result in less work done than when working remote.

"The contract sadly does not say work is remote" Question answered. Your commuting time cannot be used as an excuse to work less, because you agreed to it when signing the contract.

Are we sure this is a real question? it has generated a lot of comments and answers, but the OP has not participated in any of them. Actively participating and answering the questions posted in comments is a good sign that the question is serious, but in this case the OP seems to have vanished completely. Starting to wonder if the question is real.

Trying to force your engineers to be on a call at night and on weekends without extra compensation is the fastest way of seeing them leave. I would recommend not trying to implement this, otherwise your next major concern will be finding new engineers to replace the ones leaving.

Check that the document don't contain a clause forbidding you from working for a competitor for the next X years. That would limit your options of finding a new position.
