Creating views with joins in PostgreSQL - database

Question

For a small shift management project I decided to make I'm trying to make a weekly schedule of shifts for our employees, based on a 3 shifts per day schedule, where 1 shift can hold more than one employee.
I've created an employee table and a work_day table that holds the date of the shift and 3 join tables for each shift of the day.
CREATE TABLE employee(
id SERIAL PRIMARY KEY,
"name" VARCHAR(128) NOT NULL,
archived BOOLEAN DEFAULT FALSE
);
CREATE TABLE work_day(
id SERIAL PRIMARY KEY,
"date" DATE NOT NULL UNIQUE
);
CREATE TABLE morning_shift(
employee_id INTEGER FOREIGN KEY REFERENCES employee(id),
shift_id INTEGER FOREIGN KEY REFERENCES work_day(id),
PRIMARY KEY(employee_id, shift_id)
);
CREATE TABLE evening_shift(
employee_id INTEGER FOREIGN KEY REFERENCES employee(id),
shift_id INTEGER FOREIGN KEY REFERENCES work_day(id),
PRIMARY KEY(employee_id, shift_id)
);
CREATE TABLE night_shift(
employee_id INTEGER FOREIGN KEY REFERENCES employee(id),
shift_id INTEGER FOREIGN KEY REFERENCES work_day(id),
PRIMARY KEY(employee_id, shift_id)
);
The plan I had in mind is to create a view that would materialize a presentation of a work day:
Date
Morning Shift(name1, name2)
Evening Shift(name3, name4)
Night Shift(name5)
That way I can query whole work days as objects in my projects.
The issue is I come with very little experience in databases and it has been proved way more difficult that I had even imagined. I've been trying for the last couple of days and finally gave up on my ego and now I seek your humble help, how do you create a view like that. There are many confusing joins to it I can't wrap my head around it.
Thank you very much in advance.

As others mentioned in the comments, there is room for improvement regarding the DB design. However, this is how to create a view, just join all the tables where you need data from and select the fields you want:
CREATE VIEW shifts AS
SELECT *
FROM work_day inner join morning_shift on work_day.id = morning_shift.shift_id
inner join evening_shift on work_day.id = evening_shift.shift_id
... (more joins)
