Between a muslim and a non-believer is his prayer.
This means that you should guard your prayers with the utmost importance. You do not want to find that on the day of judgment that your job was your shirk, and find yourself among the non believers.
Islam has many ways to make this practice easy for you.
If the work is more than 24 miles away, so that traveling there and back will take you 48 miles then you should be shortening your prayers and this will make it easier.
In this case you can also combine your prayers (duhhr and asr, as well as magrib and isha)
This is not compulsory for a traveler but is something you can do if you have a good reason to do so.
To do this you would pick a time within the windows of Dhuhr and Asr
You would make your intention to pray Dhuhr and pray two rakat (Dhuhr is shortened due to traveling) then following that, make your intention to pray Asr and pray two rakat.
This is done in a similar way for Maghrib and Isha
Though magrib is not shortened.
If you arrive home before you've prayed Maghrib but it is time for isha, then you can still combine them, but do not shorten the Isha salah.
What this means is that you would only need to find one time for salah during your travel to work or while you are at work.
Since you aren't very clear about what exactly is preventing you from salah I cant really help with that. But i know that amy situation Allah puts you in will present some instance in which you can keep your responsibility to Him.
Find a stair well or a parking lot or anyplace really.
Allah has made the entire world a place for salah.
If you really cannot find a place to do it, for a valid reason, i.e. Because you are afraid and not just because you are embarrassed, then you can pray while on the bus.
May Allah make it easy for you and guide you to maintaining your salah.
