Python selenium: running into StaleElementReferenceException

I am trying to scrape all job postings for the last 24 hours from Glassdoor and save them to a dictionary.

binary = FirefoxBinary('path_to_firebox_binary.exe')
cap = DesiredCapabilities().FIREFOX
cap["marionette"] = True
driver = webdriver.Firefox(firefox_binary=binary, capabilities=cap, executable_path=GeckoDriverManager().install())

base_url = 'https://www.glassdoor.com/Job/jobs.htm?suggestCount=0&suggestChosen=false&clickSource=searchBtn' \
       '&typedKeyword=data+sc&sc.keyword=data+scientist&locT=C&locId=1154532&jobType= '
driver.get(url=base_url)
driver.implicitly_wait(20)
driver.maximize_window()
WebDriverWait(driver, 20).until(
        EC.element_to_be_clickable((By.CSS_SELECTOR, "div#filter_fromAge>span"))).click()
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((
        By.XPATH, "//div[@id='PrimaryDropdown']/ul//li//span[@class='label' and contains(., 'Last Day')]"))).click()

# find job listing elements on web page
listings = driver.find_elements_by_class_name("jl")
n_listings = len(listings)

results = {}

for index in range(n_listings):
    driver.find_elements_by_class_name("jl")[index].click()  # runs into error
    print("clicked listing {}".format(index + 1))
    info = driver.find_element_by_class_name("empInfo.newDetails")
    emp = info.find_element_by_class_name("employerName")

results[index] = {'title': title, 'company': emp_name, 'description': description}

I keep running into the error message

selenium.common.exceptions.StaleElementReferenceException: Message: The element reference of is stale; either the element is no longer attached to the DOM, it is not in the current frame context, or the document has been refreshed

for the first line inside my for loop. Even if the for loop runs for some number of times, it eventually leads to the exception showing up. I am new to selenium and web scraping, will appreciate any help.
