Our office shop door is not latching automatically when it closes. Now
we have to push the door in order for it to latch. Somehow the latch
is a lot tighter than before. Is it possible to adjust it easily?

I have uploaded some pictures showing the door, latch and strike

Call a locksmith to disassemble the lock and lubricate it properly
with
grease on the inside of the lock case...

Spraying any type of lube on the outer surfaces of the latch will only
be at best a temporary solution...

The locksmith may find that one of the internal springs of the latch
has become dislodged or is broken...

You can also adjust the "latch speed" on the door closer to use more
force to close the door...

Your particular problem can be caused by: poor alignment of the door
in the frame, a tired door closer which is getting ready to give out,
or
an issue with the latch itself...

You have ruled out door alignment as an issue as shown by your pics,
so your problem is being caused by some combination of the other
two...

P.S. WD-40 is not a permanent lubricant, sure it will help for about
24
hours, but after that it is mostly evaporated and will do nothing to
help
keep the innards in a lock case lubed... In fact it may very well
dislodge
gobs of dirty grease with grit on it and make the problems worse...

Taking the lock case apart to properly clean it and then lubricate it
with
grease as it was done at the Adams Rite factory when the unit was new
is what is called for here, not blindly spraying magical solvents and
water
displacement chemicals in from the gaps around the latch...
